IEC photoelectric receiver: normally open receiver 3 wire with connector
Photoelectric receiver form: Normally Open Receiver 3 wire with connector.
In plain English
What does IEC photoelectric receiver: normally open receiver 3 wire with connector mean?
A photoelectric receiver evaluates light arriving from an associated emitter and provides the documented electrical response. This entry identifies the normally open receiver 3 wire with connector form in the publisher's IEC-context family.
A simple example
An object crossing a conveyor beam can change the receiver output. The receiver tag should identify its optical partner and the controller input receiving its signal. The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state. The three-wire form distinguishes supply, return and switching output. Confirm sourcing or sinking operation from the actual sensor circuit before connecting it to an input.
What the drawings help you do
The connector variant adds a separable field interface. Keep the mating connector designation, pin numbers and cable-core mapping visible at that boundary. Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.
This particular reference
Photoelectric receiver form: Normally Open Receiver 3 wire with connector. This entry adds the normally open receiver 3 wire with connector detail to the broader photoelectric receiver family. Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.

How to read it
- The normally-open designation starts with a non-conducting output or open contact in the documented reference condition; operation changes that state.
- The three-wire form distinguishes supply, return and switching output. Confirm sourcing or sinking operation from the actual sensor circuit before connecting it to an input.
- The connector variant adds a separable field interface. Keep the mating connector designation, pin numbers and cable-core mapping visible at that boundary.

Information to show or reference
- Identify the target, sensing mode and expected normal condition.
- Label supply, output and connector pins from the actual device diagram.
- Reference output circuit type, operating range and controller input.
A distinction that matters
This entry adds the normally open receiver 3 wire with connector detail to the broader photoelectric receiver family. Normally-open and normally-closed labels describe the documented electrical output form. They do not by themselves establish light-on or dark-on operation; confirm that setting with the device data.
